UN TED STATES PATENT OFFICE,

RICHARD HENRY BRIGGS AND CLEVELAND PRIOHARD, OF WHISTLER, ALA.

CAR,

SPECIFICATION forming part of Letters Patent No. 294,574, dated March 4,1884.

' Application filed July 20,1883. (N0 mode Be it known that we, RICHARDH. BRIGGS and CLEVELAND PRIOHARD, of Whistler, in the county of Mobileand State of Alabama, have invented certain new and usefulImprovements-in Cars; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the artto which it pertains to make and use it,reference being had to the which form part of this specification.

Our invention relatesto an improvement in cars for the transportation ofvegetables,

fruit, and other perishable matter; and itconsists in the combination-ofa car which has suitable openings throughits ends and sides, withsections of flooring which are so constructed as to allow freeventilation, and sections of slats or sheathing which are secured to theinside ends and sides of the car, all of which will be more fullydescribed hereinafter.

The object of our invention is to provide a ventilated car in whichperishable articles of all kinds can be transported, and through which aconstant and perfect circulation of air is Figure 1 is a side elevationof a car embodying our invention, partly in section. Fig. 2 is an endview of the same, partly in section. Fig. 3 is a horizontal section.

A represents an ordinary car, of any desired construction that may bepreferred. Through each end of this car, about on a line witheach other,are the openings B, which are covered with wire-netting'of any suitablekind. Through the sides of the car, upon each side of the central doors,D, are made suita-' ble openings, F, which are barred'or covered withlattice-work of any kind, and which serve to carry off all of the gasesor foul air which settle upon the floor of thecar, and to allow a freeand perfect upward ventilation of the air through the car.

The flooring is 'composed'of the sections H, and these sections consistof a number of cross-bars, I, which are perforated at different pointsto allow the air to pass freely through,

car.

and which have a number of slats, J, secured to their upper edges. Theseslats are separated from each other sufficiently far to allow the air topass freely through. The. central section of the floor between the twodoors preferably runs at right angles to the other two sections, asshown in Fig. 3. This construction allows the sections ofv the flooringto be readily removed at any time, either for the purpose of cleaningthe car or for the purpose of removing the flooring when the car is tobe used for other purposes than the transperishable articles from beingpiled or packed in the car in such a manner as to interfere with thecirculation of theair at any point. The air is then left free to pass upunderneath. the articles, or through from the sides of the car.

'Upon the top of the car, at opposite ends, are placed suitableventilators, 0, through which the currents of air which pass into thecar from the ends and at the bottom make their escape. While the car isin motion a partial vacuum is formed in the ventilators, and the airnaturally flows directly toward and through them. The air, it will beseen, is thus'pa'ssing constantly through the ends and sides of the car,and rising up through the perishable articles and passing out throughthe top.

Having claimv 1. The combination of the car with secthus described ourinvention, we

' tions of flooring which are placed in the ends of the car, and thesection of flooring which is placed at right angles thereto, eachsection being composed of the perforated cross-bars I and the slats J,and the car being provided This lattice-Work prevents fruit or otherwith the ventilating-openings F B below the In. testimony whereof weaffix oursignatnres level of the sections, substantially as shown. inpresence of two witnesses.
